Well... as most of you see PF is trying to get some real coins from your pocket but what I feel is actually the opposite way.
1) They ever want to handle/supervise the trading 'market' and it seems they are not eager to do so. It's obvious that if they are going to control the trading, it cost them more. And as the rep. system... the trader had been too depend on it and even made it as a safe index but it never should be. Is good for the on going trade market to remove it due to people made fake rep by handling 1/2 giveaway, as well as the most serious problem: some huge "little" group... mostly were teens they made fake trade and rep each other and prepare some gang scam right after the cheating trick was widely be reported and at the same time huge amount of newbies rushed into the forum cause PF highlightly introduced it to the public when login to the game (and as i know one of the group they have over 100 members!!!!!)
And if PF wants players to spend real money then they should encourage players to trade rares in the forum (but al of us can see they have no intend to do so) OR to issue "gold items" that you can buy with real money (like fluff friends) but they didn't. They even reduce the price of the new jukes/lips instead~
So it is no way to prevent trades between players and at the same time want to gain your $$.
Sorry for my lousy english but I hope you can (fairly) understand what I want to say~
